Description

A flaw was found in the OCFS2 (Oracle Cluster File System, version 2) component of the Linux kernel. A local attacker with control over a specially crafted filesystem could exploit a vulnerability in the `ocfs2_group_extend` function. This flaw arises from an insufficient validation of a global bitmap inode block, allowing a crafted filesystem to bypass structural validation. Successful exploitation leads to a kernel crash, resulting in a denial of service.
